Visual rating scales for age-related white matter changes (leukoaraiosis): can the heterogeneity be reduced?

BACKGROUND AND PURPOSE: It has been hypothesized that the use of different visual rating scales partly explains the discordant results of studies investigating risk factors and clinical correlates of age-related cerebral white matter changes (leukoaraiosis). We aimed to compare 6 widely used rating scales for leukoaraiosis and to calculate conversion coefficients of the score of 1 scale in the score of a second scale. METHODS: Two trained raters evaluated 80 pairs of CT and MRI scans using 2 CT and 4 MRI rating scales for white matter changes. Correlations among the scales were evaluated and regression lines were constructed with each of the CT and MRI scale scores as variables. RESULTS: A high correlation was observed in all the paired comparisons of the 6 scales (Spearman's rho ranging from 0.85 to 0.96, P<0.0001). Using regression analysis, we determined numeric parameters to transform the score of 1 scale to the corresponding score for each of the remaining scales and relative confidence intervals. The predictive values of these conversions expressed as R(2) ranged from 0.75 to 0.92. CONCLUSIONS: The present findings support the view that a good correlation exists among the considered visual rating scales for white matter changes. With the limitation that conversion parameters are calculated by applying a linear regression to partly nonlinear scales, their use allows comparison of the results of previous studies that used different scales and to pool data from past and ongoing clinical trials.

Cerebrovascular disease in Italy and Europe: it is necessary to prevent a 'pandemia'.

In Italy and Europe, strokes are the third most common cause of death and resulting invalidity. In the ever-increasing 80-years-old-and-over people, strokes become more serious due to the clinical presentation during the acute phase and the ten-times higher mortality, but also in relation to the twice as high resulting disability as for younger subjects. However, stroke prevention is possible both through correct behavioural habits and pharmacological means. Besides the well-known preventive effects of an adequate anti-hypertensive, anti-diabetic and/or anti-aggregant/anti-coagulant therapy, there are increasing evidences of the effectiveness of the anti-hypercholesterolemic therapy in stroke prevention. Moreover, a great part of the risk factors for the cerebrovascular disease coincides with those for cardiovascular disease, for which the correction of the former automatically involves a reduction in incidence of both pathologies. In this context, a statin's rational use can therefore represent an important tool for the combined prevention of the two pathologies. Finally, different hypotheses link the origin of Alzheimer's disease to that of progressive cerebrovascular dementia caused by cerebral microcirculation damage. It is plausible that the application of a suitable early prevention of the cerebrovascular pathology could bring to a more late slatentisation and less serious demonstrations of Alzheimer's disease, when this is destined to develop.

Cerebrovascular disease in Italy and Europe: it is necessary to prevent a 'pandemia'.

In Italy and Europe, strokes are the third most common cause of death and resulting invalidity. In the ever-increasing 80-years-old-and-over population, strokes become more serious due to the clinical presentation during the acute phase and the ten times higher mortality, but also in relation to the twice as high resulting disability as for younger subjects. With the growing number of ailing and not-self-sufficient elderly, other resources will have to be relocated to this field of public health. Then, the dependence index and the ensuing equivalence based on estimates for the first decades of 2000 will create more difficulties in retrieving the funds for social policies. However, stroke prevention is possible both through correct behavioural habits and pharmacological means. Besides the well-known preventive effects of an adequate antihypertensive, antidiabetic and/or antiaggregant/anticoagulant therapy, there is increasing evidence of the effectiveness of statin therapy in stroke prevention. Subjects with a personal history of cerebrovascular events have an increased coronary risk and vice versa. The greatest part of the risk factors for the cerebrovascular disease coincides with those for cardiovascular disease, for which the correction of the former automatically involves a reduction in incidence of both pathologies. In this context, a statin's rational use can therefore represent an important tool for the combined prevention of the two pathologies. Finally, different hypotheses link the origin of Alzheimer's disease to that of progressive cerebrovascular dementia caused by cerebral microcirculation damage. The aim of this review is to resume the actual knowledge about the epidemiology of cerebrovascular disease in Italy and Europe, and about the means available to prevent this phenomenon.

Intravenous glycoprotein IIb/IIIa inhibitor (tirofiban) followed by intra-arterial urokinase and mechanical thrombolysis in stroke.

BACKGROUND AND PURPOSE: The purpose of this study was to evaluate preliminarily the efficacy and safety of intravenous tirofiban combined with intra-arterial pharmacologic and mechanical thrombolysis in patients with stroke. METHODS: Twenty-one consecutive patients with an acute ischemic stroke due to major cerebral arteries occlusion and a National Institutes of Health Stroke Scale [NIHSS] score > or = 18 were treated with an intravenous bolus of tirofiban and heparin followed by intra-arterial administration of urokinase coupled with mechanical thrombolysis. RESULTS: Thirteen patients had an anterior circulation stroke (T-siphon internal carotid artery [ICA] = 7; middle cerebral artery [MCA] = 6), 6 patients a posterior circulation stroke, and 2 patients an anterior plus posterior circulation stroke (left ICA or M1 tract of MCA plus basilar artery occlusions). Mean NIHSS score on admission was 21 (range, 18-27). Immediate recanalization was successful (thrombolysis in myocardial infarction [TIMI] 2-3) in 17 of 21 patients. The following day, 14 of 19 patients improved substantially and complete vessel patency (TIMI 3-4) was confirmed by digital subtraction angiography. Intracranial bleeding occurred in 5 of 21 patients (3 symptomatic cerebral hemorrhages and 2 subarachnoid hemorrhages) and was fatal in the case of 3 patients. At discharge, the mean NIHSS was 5.4 (range, 0-25). Overall, at 3-month follow-up the functional outcome was favorable (modified Rankin Scale score = 0-2) in 13 of 21 (62%) patients. Death (including all causes) at 90 days occurred in 6 of 21 (28%) cases. CONCLUSIONS: The combination of intravenous tirofiban with intra-arterial urokinase and mechanical thrombolysis may be successful in reestablishing vessel patency and result in a good functional outcome in patients with major cerebral arteries occlusions.

[Prevalence of dementia in Tuscany: results from four population-based epidemiological studies].

OBJECTIVE: to provide information on epidemiology of dementia in Tuscany needed to plan for dedicated health and social services. DESIGN: analysis of pooled baseline data from 4 population-based longitudinal studies. SETTING: 4 municipalities in Tuscany. PARTICIPANTS: 4,056 elderly subjects enrolled in 4 longitudinal studies. MAIN OUTCOME MEASURES: age- and sex-specific dementia prevalence rates and estimated number of demented people, by degree of cognitive impairment and BADL disability in the elderly population of Tuscany. RESULTS: out of the evaluated subjects, 293 are demented. Prevalence of dementia increases from about 1 % in the 65-69 age group to about 28 % in the 90+ age group both among women and men. About 43% of the demented study subjects suffer from severe mental deterioration (MMSE < 14) and56% are disabled in at least one Basic Activity of Daily Living (BADL). We estimate that about 19 thousand demented elderly men and 40 thousand demented elderly women are currently living in Tuscany of whom 26 thousand severely mentally impaired and 34 thousand disabled in at least one BADL. The resulting overall dementia prevalence standardised on the Italian 65+ population is 5,3% for men and 7,7% for women. CONCLUSIONS: these estimates could be used as a basis for the evaluation and the planning of social and health care services dedicated to demented people.
